European astronomers using using the XMM - Newton X - ray space scope have captured a glimpse of an unprecedented varlet galaxy that ’s dash through other galaxy at a rate of 814 miles ( 1,310 km ) per second .
The nerveless and compact arrangement is locate 1.4 billion light - years away , so this go on a long , foresighted time ago . As National Geographic isreporting , the bullet galaxy weighs about 200 trillion times as much as Earth , but it ’s travel at 0.44 % the speed of light as it ploughs through the Abell 4067 cluster of galaxies .
“ The bullet start right through the cardinal neighborhood of the cluster without being disrupt and we can clear watch over the cognitive operation how the bullet portion is stripped of its layers outside the gist , ” compose researchers Gayoung Chon and Hans Boehringer in their study . “ There is an indication of a shock heated region in the East of the cluster with a higher temperature . ”
Further observations of the bullet , which is center by a massive other type beetleweed , will help scientists sympathise how these monolithic celestial collisions spread out and how much these removed galaxies weigh . In addition , the stargazer are hop to know how much gas smother the bullet and what the shock wave make by the hit must have looked like .
The newspaper publisher is set to appear in an upcoming edition of Astronomy and Astrophysics , but you may register it at the pre - print archive rightnow .
